On Yom Kippur (Day of Atonement), when the High Priest would enter the Holy of Holies, he did not dress in his usual clothing for serving the Lord. He laid aside all the precious stones set in gold, the gold crown and special hat, the colourful ephod and blue robe...
One day a year (Day of Atonement / Yom Kippur), the High Priest would enter through the third veil into the Holy of Holies, with hot holy coals, incense, and blood (Lev.16). This veil had golden Cherubim embroidered on it. A picture, or reminder, of the Cherubim God placed east of Eden guarding the way back to the Tree of Life (Ex.26:31; Gen.3:24).
Every morning and evening, the High Priest would enter through the second veil which was the entrance to the Holy Place. Each time he had to bring fresh hot coals from the sacrificial altar along with a special mix of incense for the golden altar, and he had to refill the crushed, pure oil in the seven lamps of the Menorah and trim the wicks so it would keep burning.
God created us to be His earthly family, but we joined the rebellion against God. We (mankind) listened to the voice of Satan and disobeyed God’s specific instructions and we became unholy, so He expelled us from His presence (Genesis 3).
